State determination in continuous measurement
A. C. Doherty, S. M. Tan, A. S. Parkins +1
The possibility of determining the state of a quantum system after a continuous measurement of position is discussed in the framework of quantum trajectory theory. Initial lack of…
Theory of strong outcoupling from Bose-Einstein condensates
Robert Graham, Dan F. Walls
We study the dynamics of a magnetically trapped Bose-Einstein condensate in the presence of an external electromagnetic field coupling trapped, untrapped and antitrapped Zeeman sub…
Dynamical quantum noise in Bose-Einstein condensates
M. J. Steel, M. K. Olsen, L. I. Plimak +5
We introduce the study of dynamical quantum noise in Bose-Einstein condensates through numerical simulation of stochastic partial differential equations obtained using phase space…
Detection of vorticity in Bose-Einstein condensed gases by matter-wave interference
Eric L. Bolda, Dan F. Walls
A phase-slip in the fringes of an interference pattern is an unmistakable characteristic of vorticity. We show dramatic two-dimensional simulations of interference between expandin…
Non-Markovian quantum trajectories for spectral detection
M. W. Jack, M. J. Collett, D. F. Walls
We present a formulation of non-Markovian quantum trajectories for open systems from a measurement theory perspective. In our treatment there are three distinct ways in which non-M…
Measurement of relative phase diffusion between two Bose-Einstein condensates
Janne Ruostekoski, Dan F. Walls
We propose a method of measuring diffusion of the relative phase between two Bose-Einstein condensates occupying different nuclear or spin hyperfine states coupled by a two-photon…
